I noticed that there was a new "E for Climax" control in the scene menu, so I decided to try it out. Unfortunately that caused me to be unable to hide/unhide the informational text (Ctrl) or exit the scene (Space). Other controls, including changing focus (WASD), first-person (F1), and changing camera mode (Shift) still worked.

It does look, however, that in the scenes where climax is implemented, this is not an issue.

Thanks for the report, it sounded strange at first that simply having an animation trigger set could cause this, as the code doesn't do anything but that, but it looks like I missed adding an array size check to see if there are any triggers at all, as trying to access a 0 sized array throws an exception! All fixed now :)
